AI Technical Summary

Technical Problem

In material handling systems, particularly in sorter systems like tilt-tray and cross-belt sorters, accurate calibration of carrier transmitter boards (CTBs) and motor control boards (MCBs) is challenging due to installation inaccuracies, leading to incorrect command delivery and actions, which can result in errors and inefficiencies.

Method used

An auto-calibration method that involves transmitting a short discharge command based on a clock offset, modifying the clock offset until the command is correctly received by the intended MCB, and configuring the sorter control system accordingly, allowing for accurate calibration without manual intervention.

Benefits of technology

This method enables precise calibration of the sorter control system, ensuring accurate command delivery and improving the overall performance and efficiency of the sorter system by automatically adjusting clock offsets until the correct position is identified.

Abstract

A method for auto-calibration of a sorter is described. The method includes transmitting, by a carrier transmit board of a sorter, a short discharge command to a first section of the sorter. The short discharge command can be generated based on a first clock offset. Further, the method includes receiving at the carrier transmit board a status message indicative of a status of a first motor control board associated with the first section of the sorter. Furthermore, in response to the status message indicating that the first motor control did not receive the short discharge command, the method includes modifying the first clock offset to a second clock offset and retransmitting the short discharge command based on a second clock offset. If the first motor control receives the short discharge command, the method includes configuring a sorter control system based on the first clock offset.
